Isolated thunderstorms will form over the mountains, Northern California and the Klamath Basin in the afternoon and evening. Some dry lightning will accompany the storms, along with gusty winds.

Sunday, a cool front will encroach much of Southern Oregon and Northern California, with the brunt in Northern Oregon and Washington.

Some showers and thunderstorms, along with gusty winds will be pervasive in the Klamath Basin.

Quieter weather on Monday will allow for cooler than average temperatures and partly cloudy skies. The next chance for a few showers will mainly be over the mountains, later in the week
